Here is the log in /var/log/libvirt/qemu/centos_heavy.log<br /> <br /> qemu-kvm: /builddir/build/BUILD/qemu-kvm-0.12.1.2/qemu-char.c:630: io_watch_poll_finalize: Assertion `iwp->src == ((void *)0)' failed.<br /> 2014-01-13 16:50:31.576+0000: shutting down<br /> <br /> The code it's failing the assertion on has an interesting comment:<br /> <br /> static void io_watch_poll_finalize(GSource *source)<br /> {<br /> /* Due to a glib bug, removing the last reference to a source<br /> * inside a finalize callback causes recursive locking (and a<br /> * deadlock). This is not a problem inside other callbacks,<br /> * including dispatch callbacks, so we call io_remove_watch_poll<br /> * to remove this source. A t this point, iwp->src must<br /> * be NULL, or we would leak it.<br /> *<br /> * This would be solved much more elegantly by child sources,<br /> * but we support older glib versions that do not have them.<br /> */<br /> IOWatchPoll *iwp = io_watch_poll_from_source(source);<br /> assert(iwp->src == NULL);<br /> }<br /> <br /> ------<br /> CPU Info:<br /> <br /> <a href="http://pastebin.com/U7MrzFxK">http://pastebin.com/U7MrzFxK</a> [<a href="http://pastebin.com/U7MrzFxK" target="_blank">^</a>]<br /> <br /> --------<br /> <br /> Relevant RPM versions:<br /> <br /> qemu-kvm-0.12.1.2-2.415.el6_5.3.x86_64<br /> libvirt-0.10.2-29.el6_5.2.x86_64<br /> <br /> --------<br /> <br /> Domain config:<br /> <br /> <a href="http://pastebin.com/Nf2VsER8">http://pastebin.com/Nf2VsER8</a> [<a href="http://pastebin.com/Nf2VsER8" target="_blank">^</a>]<br /> <br /> (Note the use of the vmchannels; I believe this is playing a part in this crash)<br /> <br /> ---------<br /> <br /> uname -a:<br /> <br /> Linux blizzard 2.6.32-431.3.1.el6.x86_64 <a href="http://bugs.centos.org/view.php?id=1">0000001</a> SMP Fri Jan 3 21:39:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux<br /> <br /> ---------<br /> <br /> CLI to start guest (included in attached dump):<br /> <br /> <a href="http://pastebin.com/W01Xzyb0">http://pastebin.com/W01Xzyb0</a> [<a href="http://pastebin.com/W01Xzyb0" target="_blank">^</a>]<br /> <br /> ---------<br /> <br /> thread apply all bt:<br /> <br /> <a href="http://pastebin.com/FTpUDU7A">http://pastebin.com/FTpUDU7A</a> [<a href="http://pastebin.com/FTpUDU7A" target="_blank">^</a>]
